So, my "new" pedal assembly from Brewer's arrived at my house while I'm still on the road, and I have some questions about swapping the assemblies so it'll speed things up when I finally get around to doing it. I do plan on going with a hydraulic throwout bearing, so that bypasses anything I would have asked about the Z-bar stuff. Will I need anything extra as far as the pedal assemblies themselves go? How long will it typically take? Will I need to visit a chiropractor after I'm done?
